Features of laminated glass
The laminated safety glass is two or more layers of glass is sandwiched with the plastic material intermediate film, polyvinyl butyral panel (PVB), polycarbonate panel, polyurethane panels, acrylate plate and other plastic materials, made by the high temperature and high pressure processing. Commonly used laminated glass products intermediate material is polyvinyl butyral (PVB) film. Laminated glass is an excellent safety glass, which is firmly bonded together by two or more sheets of glass using an adhesive material. It has transparent, high mechanical strength, heat resistant, cold resistant, sound insulation and anti-UV performance. The glass and adhesive material combination ensures the laminated glass to have good resistance to impact and safety performance at crushing. When laminated glass is impacted and broken, the fragments will be stuck by the adhesive material, just forms cracks but not easy wounding, which also maintains the original shape and visibility. Due to the above-mentioned advantages, laminated glass has been widely used in the construction, automotive, ship-to-ship, aircraft.
How do consumers to buy high-quality laminated security glass? Professionals give the following suggestions:
1. See signs and check the certificate. Buy regular factory products with 3C certification mark. Since the state carried out product certification of safety glass in 2003, laminated glass production enterprises are compulsory to carry out product certification, companies must silk screen or paste 3C logo in the body of the product for sale, or add 3C logo at the minimum outer packaging and the accompanying documentation (such as certificate of competency ).

3. Laminated glass should avoid heat exposure, humidity and rain, climate and environment before installation and use, which should be stored in ventilated, dry place to prevent the seepage of laminated glass edge.
4. During use process, you should avoid external shocks, especially to avoid the glass edge and corner impacted by external shocks. When cleaning laminated glass, be careful not to scratch, scrape or rub the surface of the glass, so as not to affect the appearance.
